The Schedule referredtq in these Letters Patentv and making part of the same.

To `all whom it may concern Be it known that I, ELIJAH H. VINING, of Covington, in the county of Newton, and State 'of Georgia,` have invented anew and useful Improvement in GrindingMills; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, referenccbcing had to the accompanying drawings forming part of this specification.

`The invention relates to an improved alarm appai ratus for warning the miller when the grain is nearly out of the hopper, and consists in the combination with a strap of leather or other flexible substance traversing the bottom of the hopper, to be pressed down by the weight of the grain when theA hopper is full, of a s1ide,rbell`clapper,and bell, held ont of action when the strap `is covered with grainby the said strap, but

` let fall when the grain passes off the strap, so that the bell-clapper will come in contact with the stone, and be agitated by it so as to strike the bell and give the alarm.

Figure 1 representsl a'sectional elevation ofthe improved milltakeu on the line xx of iig. 2,'showing the position when the hell-clapper is held above the stone;

`Figure-2 is a side elevation of the same; and

Figure 3 represents a sectional elevation through to the tube, and has a ililcrum at F, suspended from the hopper, or in any other suitable way.

The grain settles downthrough these tube-s B'G into the cup A, from which itjis caused to be discharged by centrfugalforce overthe top of the cup at all points alike, thus supplying it to the stones in the same equal way. Y.

The raising or lowering of the tube C will allow the `grain to ow overthe 'top of the cups more or less rapidly, as required.

G represents a strap of leather, cloth, vor other similar substance, permanently connected to the inside of the hopper, at H. A cord, I, is tied to the other end, and passes/ under a staple, K, and through Va small hole," L, above, in the side of the hopper M. This cord" is guided along down the hopper in guides N, and is connected to a vertical slide, O, working in any suit-able guides' on the hopper, and carrying a bellcranked hammer, I, and a spring, Q, bearing against it. The bell-hammer is pivoted to the slide, and has a pendent arm, R, reaching very nearly to the top of `the ruiming stone when the slide is up, and quite down to the edge of the eye when the slide is down.

Sis a bell, hung from the hopper so that the arm 'l of the hammer is borne against it by the spring Q. When the grain in the hopper rests on the strap G,

it will be pressed down, and will draw up the slide O and arm R ofthe hammer away from the stone, but

when it is nearly out and falls below the strap, theweight of the hammer and slide will carry them down,

so that the end of R, touching the running stone, will be moved thereby against the spring, which, when sufficiently strained; will throw the hammer back so as to strike the bell, when, coming again in contact with the stone, it will again go forward against the spring, and so on, an alarm will be kept up as long as there is no grain in the` hopper and the stone runs.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The combination with the hopper and running stone` `of the strap G, cord I, slide O, bell-hammer P, spring and bell, substantially as specified.
